The grounding monitoring device ensures the electrostatic grounding of road tankers, rail cars and Big Bag (Rev. C) while loading flammable liquids and powder. The device provides a conductive connection to the ground and monitors in parallel the quality of the electrostatic grounding. This guarantees that the electrostatic charge remains at a safe level and that no explosion hazard is generated by uncontrolled energy discharge.The following recommendation requires grounding during loading and recommends interrupting loading in case of incorrect grounding:- CLC/TR 60079-32-1 recommendation for avoiding ignition hazards due to electrostatic charges.- TRBS 727 rules for avoiding ignition hazards as a result of electrostatic charges.
